In Wm. Penn Parking Garage, Inc. v. City of Pittsburgh, 464 Pa. 168, 346 A.2d 269 (1975), the leading Pennsylvania case on standing, the Supreme Court held that a person who is not adversely affected in any way by the matter he seeks to challenge is not "aggrieved" and, therefore, has no standing to obtain judicial relief. To establish an "aggrieved" status, a party must have a substantial interest, that is, there must be some discernible adverse affect to some interest other than the abstract interest of all citizens having others comply with the law. Additionally, an interest must be direct, which means that the person claiming to be aggrieved must show causation of the harm to his interest by the matter of which he complains. Further, the interest must be immediate and not a remote consequence of the judgment, a requirement addressing the nature of the causal connection.
